FARM-GATE.

Specification of Letters Patent. Patented Dec. 21, 1920.

Application filed'october 27, 1919. Serial No. 333,458.

ful Improvements in Farm-Gates; and I do declare the following to be afull clear, and exact description of the same, reference being had tothe accompanying drawings, and

to the characters of reference marked thereon, which form a part of thisapplication.

This invention relates to improvements in gates, being particularlyintended for use on farms, etc., to be interposed in the lines of fenceswhich bound and subdivide the farm and keep livestock from straying andat the same time to allow a passage over whatever roads, trails, etc.,enter the farm from the outside or cross the various subdivisions.

The principal object of my invention is to provide a gate whose weightwill'be counterbalanced; and hence easily moved out of the way bymovement in a vertical direction, and which when moved to its fullestextent will leave an entirely unobstructed passage therethrough the fullwidth of the road.

Another object is to so construct the gate that it cannot be moved bypressure in a horizontal direction, and consequently will never have atendency to sag and scrape along the ground as is usual with swinggates.

A third object is to so construct and proportion the gate that it willremain at any position when the lifting pressure is removed so thatrelatively wide but low objects such as a flock of sheep, may pass throuh the gate to the full width of the road wit out raising it the entiredistance.

Another object of the invention is to produce a simple and inexpensivedevice, and yet one which will be exceedingly effective for the purposesfor which it is designed.

These objects I accomplish by means of such structure and relativearrangement of parts as will fully appear by a perusal of the followingspecification and claims.

In the drawings similar characters of reference indicate correspondingparts in the several views.

Figure 1 is a side elevation of the gate showing the same closed.

Fig. 2 is a similar view with the gate opened.

Fig. 3 is an enlarged fragmentary top view of the weighted gate frame.

-Referring now more particularly to the characters of reference on thedrawings, the numeral 1 denotes a railset to one side of the roadtransversely thereof and mounted on posts 2 suitably anchored in theground. Side rails 3 are also secured to the posts a short distanceabove the ground.

Adapted to straddle the rails and posts is a pair of semicircular disksor plates 4', whose center is above the top of the rails 1,

there being a roller 5 at this point between I the frames and riding onthe rail 1.

' The diametrical ends of these disks lie in a vertical plane when thegate is closed, and are adjacent the edges of the road, having top andbottom extensions 6 between each pair of which is secured the ends ofthe gate frame 7. This frame is preferably made of bent piping, suitablybraced by diagonals 8 and covered with wire mesh 9. I do not wish toconfine myself however to use this construction of gate- The gate is ofcourse adapted to extend across the road terminating adjacent a fencepost 10 on the other side thereof. A block 11 'may be positioned on theground at this point'so that the end of the gate may rest thereon. Guidestraps 12 are also mounted to the post and project beyond the end of thegate somewhat so as to aid the same in resisting side pressures thereon.

Each of thedisks 4 is provided with a side pocket 13 beyond the pivotalaxis of the roller 5, these pockets being filled with lead or a similarweighty substance suificient to counterbalance the weight of the gateitself.

An arm 14 is pivotally connected to one of the disks 4 at a suitablepoint near the periphery thereof, preferably on a 90 degree line fromthe straight end thereof, the other end being pivotally mounted on abracket 15 secured to the farthest one of the posts 2 just below therail 1.

The disks 4 extend far enough toward the ground so that very littleclearance be tween the ground and the bottom of the gate is had, theside rails 3 serving as guides for the disks to bear against.

In opening the gate, it is only necessary to exert an easy lifting forceon the gate, when it will move upward and at the same time away from theroad, the roller 5 rid ing on the rail 1. The arm 14 being fixed at oneend, the plates 4 cannot move horizontally relative to the rail 1, sincethis arm a'cts substantially as a pivotal point about movement Possibletherefore is that of the rollers on the rail, thus drawing thegate whichthe disks turn. The only horizontal away from the road as it swingsupward.

A stop pin 16 is fixed to theplate 4: at a desired poin'thereon, so asto bear on the rail 1 when the gate is in its uppermost position, and soprevent further motiondevice as substantially fulfils the object ofthe'invention as set'forth herein; a

While this specification sets forth indetail the present and preferredconstruction of the device, still in practice such deviations from suchdetail may be resorted-to as do not form a departure from the spirit ofthe inventon, as defined by the appended claims.-

Having thus described my invention what I claim as new and useful anddesire to se+ cure by Letters Patent is y y 1. Agate structurecomprising a vertical supporting frame rigidly fixed in the ground toone side of a road transversely thereof, a gate member projecting acrossthe road, plates secured to the gate and straddling the frame, a rollerbetween the plates and ridingon the top of the frame, the

plates being counterbalanced relative to the gate with the roller as thepivotal point,

zontal rail setrigidly above the ground to one side of a road andtransversely thereof, a gate member extending across the road,semicircular platessecured to the gate'and straddling the rail, a-rollerbetween the plates bearing on therail; weightson the plates beyond theroller to offset the weight of the gate,- andan arm pivotally connectedto one of the plates and to the farther end ofthe rail, whereby when thegateis raised the roller will be caused'to move along'the rail anddrawthe gate to one side oflthe oad." a l- 3. A gate} structure comprising 1a- 3' horizontal beam supported from the ground extending transverselyof aroad and to one sidethereof, a" gatemember, a roller:,fixed to'thegate and riding freely;;on the beam, and forming a pivotal point for thegate, and means connected to thegate andbeam whereby theroller will movein a definite and constantlymaintained path when the gate is movedvertically.
